@MoonlightSentinel created dlang/dmd pull request #12090 "Fix 21518 - delegates
not checked for attribute match in const arrays" fixing this issue:

- Fix 21518 - delegates not checked for attribute match in const arrays

  Const-conversion checks for delegates are forwarded to the type of
  `funcptr`. But `TypeFunction` did not implement `constConv`, causing
  the inherited `TypeNext.constConv` (which only checks const`/`shared`/...).
  to ignore the missmatched attributes.

  The bug was restricted to `const` arrays because checks for (im)mutable
  arrays didn't use `constConv` and instead failed due to the missmatched
  `deco`.
